dBugのライセンス

わからないので、開発者にメールを投げておきました。
以下あってるかどうかわからんけどがんばって書いた内容。
面倒だったのでMyにしてしまいましたが、Ourの方が適切でしたね。多分。。。

Nice to meet you.
My name is Kazunobu Itihashi. 

I'm not good at English, sorry that it is not easy to understand my English. 

I am developing the Framework of PHP(name is Maple. http://kunit.jp/maple/) 
now in Japan. I want to use your "dBug" module as the debugging function 
in the framework. 
However, because the license is not being written in the "dBug" module, 
it is not understood whether I may distribute it to my framework including it. 

May I distribute your module with my framwork?

My best regards.
